Photoacoustic spectroscopy deals with photoacoustic research and photothermic phenomenon, in particular for the development of analytical methods with applications to forensic, bioanalytical and  environmental problems, which are grouped in the so-called ¨analytical¨.  At the same time, the group is working on analytical spectroscopic methods with optical lasers. In Photoacoustic Spectroscopy, the focus is on the development of a method.
